The SBA is limited in that it is based on the average droplet size, but cannot quantify the amount of liquid droplets exiting the gas gravity section and mist extractor section. But I cannot see the algorithm you used. It is therefore necessary to design internal baffle systems to limit sloshing. At least thats what I did Edited by thorium90, 06 February 2013 - 12:07 PM. I found out that (accordingtotheoretical calculation) three minute time is sufficient. Rethinking how polymerizations are performed is anticipated to accelerate understanding of parameters and catalyst properties . 4. Mist extractor capacity is defined by the gas velocity at which re-entrainment of the liquid collected in the device becomes appreciable. Which gives me retention time calculation. Treaters are designed to break the emulsion by applying heat and retention time, causing the water droplets to coalesce and separate from the emulsion to achieve a basic sediment and water (BS&W) specification in oil. Figure 2. Development of a User Friendly Computer Program for Designing Conventional Oilfield Separators. It features the similar components and instrumentation that is used in the oil and gas industry. It just won't happen in the real world. 1991.

From Appendix A, using a gas viscosity of 0.012 cp, CD = 1.42. The design parameter, KS, in the Souders-Brown equation is an empirical parameter and is a key factor for the sizing the gas-liquid separators vessel diameter as well as for determination of the mist extractor diameter. 2. He has 40 years You could never logically expect thatall it would take is 3 minutes for two liquids to separate completely by gravity. You can learn the details and equations used from the book.

They are typically employed in oil & gas fields in downstream of wells. Discover how this hybrid manufacturing process enables on-demand mold fabrication to quickly produce small batches of thermoplastic parts. Do you have a response to this question? And you need to check to see which phase is most likely continuous. There i found that it will be enough to give 3 minretentiontime. More retention time is needed for separators that are designed to separate oil from water, as well as gas from liquid (three-phase compared to two-phase separators). Thanks chem101 for your comment. AH)0S Thank you for helping keep Eng-Tips Forums free from inappropriate posts.The Eng-Tips staff will check this out and take appropriate action. The primary separation mechanism is liquid impingement onto the wires, followed by coalescence into droplets large enough to disengage from the mesh pad. Referring to Figure 3, the effective Le may be defined in terms of separator actual length and diameter like Le=L-D. Delivered O&G upstream sector advisory services, such as production, operational readiness, commissioning, start-up, and Brownfield / Greenfield solutions for clients across Europe, Middle East, Asia and Australia.
